Two-PLL Programmable Clock Generator

with Spread Spectrum

Two-PLL Programmable Clock Generator with Spread Spectrum

■ 8-pin small outline integrated circuit (SOIC) package

■ Commercial and industrial temperature ranges

Features

■ Two fully integrated phase-locked loops (PLLs)

■ One-time programmability

For programming support, contact Cypress technical support

or send an e-mail to clocks@cypress.com

■ Input frequency range

❐ External crystal: 8 to 48 MHz

❐ External reference: 8 to 166 MHz clock

Benefits

■ Reference clock input voltage range

❐ 2.5 V, 3.0 V, and 3.3 V for CY25482

❐ 1.8 V for CY25402 and CY25422

■ Multiple high-performance PLLs allow synthesis of unrelated

frequencies

■ Wide operating output frequency range

❐ 3 to 166 MHz

■ Programmable^[1]spread spectrum with center and down

■ Nonvolatile programming for personalization of PLL

frequencies, spread spectrum characteristics, drive strength,

crystal load capacitance, and output frequencies

spread option and lexmark and linear modulation profiles

■ Application specific programmableEMIreduction usingspread

spectrum for clocks

■ V_DDsupply voltage options:

❐ 2.5 V, 3.0 V, and 3.3 V for CY25402 and CY25482

❐ 1.8 V for CY25422

■ Programmable PLLs for system frequency margin tests

■ Meets critical timing requirements in complex system designs

■ Frequency select feature with option to select four different

frequencies

■ Suitability for PC, consumer, portable, and networking

applications

■ Power-down, Output Enable, and SS ON/OFF controls

■ Low jitter, high-accuracy outputs

■ Capable of zero parts per million (PPM) frequency synthesis

error

■ Ability to synthesize nonstandard frequencies with fractional-N

capability

■ Uninterrupted system operation during clock frequency switch

■ Application compatibility in standard and low-power systems

■ Three clock outputs with programmable drive strength

■ Glitch-free outputs while frequency switching
